The compound interest on 2000 is 60.
Step-by-step explanation:
Given,
Principal (P) = 2000
Rate of interest (r) = 3%
Time (T) = 1 years
To find the interest calculated compound in 1 year.
Formula
Amount = P[tex](1+\frac{r}{100} )^{T}[/tex]
Putting the given values we get,
Amount = 2000[tex](1+\frac{3}{100} )^{1}[/tex]
= 2060
So,
The interest = 2060-2000 = 60

Angles A and B are two acute angles in a triangle. If sin A equals cosine B, what can you conclude about the triangle?
Answer:
It's a right angle triangle with 90° at C
Step-by-step explanation:
sin A = cosB when
A + B = 90
The condition that sin A equals cosine B, with A and B being acute angles, indicates that both angles are complementary and add up to 90 degrees, suggesting a right-angled triangle.
Explanation:When given the condition that sin A equals cosine B in a triangle, and both angles A and B are acute, we can determine that triangle A and B are complementary, which means they add up to 90 degrees.
This is due to the co-function identity, where sin(90° - θ) = cos(θ) and cos(90° - θ) = sin(θ) for acute angles in right-angled triangles.
If A and B are in the same triangle, and given it is a right triangle (since they are acute and the sine of one equals the cosine of the other), we can conclude that A + B = 90°, and thus, the third angle will also be 90 degrees, making the triangle a right-angled one.
John surveyed 25 of his classmates about their music preferences7 students said they like hip-hop, 13 students said they pop, and 8 students said they liked neither hip-hop nor pop musicJohn made a Venn diagram to find the number of students who like both hip-hop and pop music Evaluate John's work Did he use the Venn diagram accurately to arrive at a correct solution?
Answer:
The venn diagram is not included in the question, but il try to answer it in a general way.
We have a sample of 25 persons.
7 of them like hiphop.
13 of them like pop
8 of them do not like neither.
So in our Venn diagarm we will have two circles, one for the students that like pop and other for the students that like hip-hop.
in the pop circle we have 13 students, in the circle of hiphop we have 7 students, and outside both circles we have 8 stundents.
Now, if we add it all we get:
13 + 7 + 8 = 28,
But we have 25 students, this means that 3 of the students like both genres, hip hop and pop.
Then the circles of hip hop and pop must have an intersection, and in the intersection we must have 3 students.

a coin is flipped and a number cube is rolled what is the sample space for this experiment
Answer:
h1,h2,h3,h4,h5,h6,t1,t2,t3,t4,t5,t6
Step-by-step explanation:
h or t is the coin, the number is the die
Final answer:
The sample space for flipping a coin and rolling a number cube consists of 12 possible outcomes. The probability of event A occurring is 1/6. Events A and B are mutually exclusive as they cannot occur at the same time.
Explanation:
A coin is flipped and a number cube is rolled; the sample space for this experiment can be listed by combining each possible outcome of the coin flip with each possible outcome of the number cube roll. The coin can either be heads (H) or tails (T), and the number cube, which is a six-sided die, can land on any number from 1 to 6.
H1
H2
H3
H4
H5
H6
T1
T2
T3
T4
T5
T6
Therefore, the sample space consists of 12 possible outcomes.
For part b, event A is "either a three or a four is rolled first, followed by landing a head on the coin toss." The favorable outcomes for event A are H3 and H4. Since there are 12 possible outcomes, and 2 of them are favorable, the probability P(A) is 2/12, which simplifies to 1/6.
For part c, event B is "the first and second tosses land on heads," which is not possible since the first "toss" is actually a roll of a die. Therefore, events A and B are mutually exclusive, as they cannot occur simultaneously. The occurrence of event A does not involve a second toss of the coin and event B is not possible within the context of this experiment.

120 students in a fifth grade class are surveyed about what kinds of pets they have. Of the 120 students,
30 have a goldfish, 40 have a mouse, and 10 have a goldfish and a mouse. Using this information, answer
each of the following questions.
Let G be the event that a randomly selected student has a goldfish and M be the event that a randomly
selected student has a mouse.
What is P(G), the probability that a student in the class has a goldfish?
What is P(M), the probability that a student in the class has a mouse?
What is P(G and M), the probability that a student in the class has a goldfish and a mouse?
What is PG or M), the probability that a student in the class has a goldfish or a mouse?
Answer: P(G) = 1/4
P(M) = 1/3
P(G and M) = 1/12
P(G or M) = 1/2
Step-by-step explanation:
Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Total Students Surveyed = 120
30 have a goldfish, 40 have a mouse, and 10 have a goldfish and a mouse.
First, the the probability that a student in the class has a goldfish
P(G) = 30/ 120
= 1/4
second, the probability that a student in the class has a mouse
P(M) = 40/120
= 1/3
Third, the probability that a student in the class has a goldfish and a mouse
P(G and M) = 1/4 x 1/3
= 1/12
Fourth the probability that a student in the class has a goldfish or a mouse
P(G or M) = P(G)+ P(M) - P( G and M)
= 1/3+ 1/4 - 1/12
= 6/12
= 1/2

Mike purchased a round wall clock the clocks radius is 10m what is the circumference of the clock
Answer:
62.8 m
Step-by-step explanation:
The circumference of the clock is the circumference of a circle which is given by
2 Pi r
Where
Pi = 3.14
Radius r = 10m
Therefore
Circumference = 2 x 3.14 x 10
= 62.8 m
The circumference of the clock is approximately 62.8 meters.
Explanation:To find the circumference of a circle, you can use the formula C = 2πr, where C is the circumference and r is the radius of the circle. In this case, the radius of the clock is given as 10m. Substituting this value into the formula, we have C = 2π(10) = 20π. The approximate value of π is 3.14, so the circumference of the clock is approximately 20(3.14) = 62.8m.
To find the circumference (C) of a round wall clock, you can use the formula C = 2πr, where π (pi) is approximately 3.14 and r is the radius of the clock. In this case, the radius is given as 10 meters. Substituting this value into the formula, the circumference is calculated as C = 2 * 3.14 * 10 meters, which equals 62.8 meters.
Therefore, the circumference of Mike's round wall clock is approximately 62.8 meters. This value represents the total distance around the edge or perimeter of the circular clock face.

Part B. What are the coordinates of the point D after a dilation with a scale factor of 5, centered at the origin?
A. D’(0,2)
B. D’(0,5)
C. D’(0,10)
D. D’(10,0)
Answer:
Part A C = (10,5) Part B C. D'(0,10)
Step-by-step explanation:
Part A
Since c is at the point (2,1) in relation to the origin, we can multiply those distances by our scale factor of 5
(2,1) * 5 = (10,5)
The new point C is going to be (10,5)
Part B
If you dilate with a factor of 5 -- relative to the origin -- you have to multiply the distance from the origin by 5.
In this case, point D is already on the y axis, so it's x value wouldn't be affected. Point D is currently 2 units away from (0,0), so we can multiply 2*5 to get 10 -- our ending point is (0,10)

How do I tell the difference between sss and sas?
SSS (Side-Side-Side) requires three pairs of equal sides to prove triangle congruence, while SAS (Side-Angle-Side) requires two pairs of equal sides and one pair of equal included angles.
Explanation:In mathematics, specifically in geometry, SSS (Side-Side-Side) and SAS (Side-Angle-Side) are two methods used to determine if two triangles are congruent. Congruent triangles are triangles that have the same size and shape.
SSS (Side-Side-Side)
The SSS criterion states that if all three sides of one triangle are respectively equal in length to all three sides of another triangle, then the two triangles are congruent. You do not need to know any angle measurements.
SAS (Side-Angle-Side)
The SAS criterion states that if two sides and the included angle (the angle between the two sides) of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.
To distinguish between the two, remember that for SSS you're comparing three sides, and for SAS you're comparing two sides and the angle that is between them.

Given:
m∠WYX = 20°
m∠XYZ = 135°
To find:
The measure of arc WXZ.
Solution:
m∠WYZ = m∠WYX + m∠XYZ
m∠WYZ = 20° + 135°
m∠WYZ = 155°
The measure of inscribed angle is half of the intercepted arc.
[tex]$\Rightarrow m \angle WYZ = \frac{1}{2} m (ar WXZ)[/tex]
[tex]$\Rightarrow 155^\circ = \frac{1}{2} m (ar WXZ)[/tex]
Multiply by 2 on both sides.
[tex]$\Rightarrow 2\times 155^\circ = 2 \times \frac{1}{2} m (ar WXZ)[/tex]
